PISTON-PACKING.

SPECIFICATION forming part of Letters Patent No. 341,138, dated May 4, 1886.

Application filed March 4, 1886. Serial No. 193,975. (No model.)

To all .whomit may concern.-

Be it known that we, CHRISTIAN GOELLER and JOHN J. MOORE, citizens of the United States, residing at Portsmouth, in the county of Scioto and State of Ohio, have invented certain new and useful Improvements in Piston- Packing; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereomwhich form a part of this specification.

This invention relates to certain improvements in metal packing for steam-cylinders, which will be hereinafter more fully described, and pointed out in the claim.

In the drawings herewith accompanying and forming part of this specification, Figure I is a side view of the piston, having a part broken away to show the interior and crosssection of the rings, 8:0. Fig. II is an end view of Fig. I, showing the interior parts. Fig. III is a perspective View of the spider removed. Fig. IV is a perspective view of the springseat and a leaf-spring.

A is the spider, such as is now in common use.

B is the bull-ring, with an l -offset on each side, over which the packing-rings are fitted; C, the follower, attached by bolts b to the spider A, holding the bull-ring B firmly in its place. The packing-rings B B fit loosely, so that they may be easily adjusted to fit any size of cylinder.

c c c c are nuts for regulating the springs.

D D D D are coiled springs, which press against the leaf-springs D D D D, which latter springs act upon the spring-seats E E, &c., by means of which action both sets of steamrings 13 B are adjusted.

c 0 c c arejam-nuts to hold the nuts 0 c c c in their positions.

G G are fiat springs to be used when sectional packing-rings are employed.

H is the piston-rod.

O is the follower-plate, which is left off in Fig. II, to slgow the interior, but which is to be attached by bolts to be fitted into holes 2 i i i, &c. The bolts 6 are fitted into square sockets e in the spider A, and the other ends pass loosely through the fiat leaf-springs D D D, 850., and spring-seats E E, &c.

d d are lugs on the spring-seats E E, 820., which pass through corresponding openings, 1), in the bull-ring B, and which act against the packing-rings B B or the flat springs G G, as the case may be.

Operation: The packing is adjusted to fit a cylinder by turning the nuts 0 and securing them in position by the jam-nuts c. This compresses the coilsprings D and leaf-springs D, which act upon the spring-seat E. The lugs (Z d, passing through the openings in the bullring, press against the steam-rings, or the fiat springs G G, in case sectional packing is used, and forces them out to fit the cylinder. \Vhen the rings become worn, all that is necessary is to extend them by means of the nuts 0. Thus, by proper adjustment with these nuts, the packing may be made to fit cylinders that have become worn out of proper shape. This packing will cause very little wear in the cylinders and keep them in good shape, and by neatly fitting the cylinder at all times very little, if any, steam will be wasted by blowing through, and as the coiled springs cause but very little friction less steam is required, and consequently there will be a saving of fuel. As there is less wear in the cylinder and the easy adjustment to fit any irregularity, the cylinder will not require to be so often bored out.

\Ve claim- In packing for cylinders, the combination of the bull-ring 13, having an L -offset on each side, the said ring having openings 1), the packing-rings B, the seats E, having the lugs d, which pass through openings 1), the springs D and D, the bolts 6, nuts 0 c, spider A, and followers C and L, as set forth.

In testimony whereof we affix our signatures in presence of two witnesses.

CHRISTIAN GOELLER. JOHN J. MOORE.
